// This application will read an initialization file with anonymous keys, disjointed sections
// and disjointed keys.
// It will collect the key values in each section found and then display the found data
// alphabetizing the section names and the key names within each section.
// Same as the `basic.js` example, except that there is some bad data, data that
// does not follow the defining SABNF grammar.
// This demonstrates how "error productions" can be used to ignore and/or report bad data.
// See, for example, `BadSectionLine`, `BadValueLine`, `BadBlankLine`.
